Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of ...

ON Semiconductor introduced the NCP1901, an integrated circuit that combines both a power factor correction (PFC) controller and a resonant half-bridge controller in a single package. The high level ...

By eliminating current sensors without sacrificing efficiency, researchers have shown a new way to build smaller, cleaner, ...

Single-phase power factor correction (PFC) circuits--a kind of front-end AC/DC converters--are ubiquitous in a variety of consumer electronic devices, including laptop adapters, LED driver power ...

Researchers have proposed a new way to control power factor correction circuits that could lead to sensorless power control.

This post sponsored by Texas Instruments. UCC28019A is an 8-pin active Power Factor Correction (PFC) controller that uses boost topology while operating in Continuous Conduction Mode (CCM). There is ...

Front end topology and some tips to design a mixed bridge circuit that effectively protects the design from an overvoltage. A robust solution using a new SCR generation and front end topologies that ...

At $3,000, the McIntosh MIP200 Power Controller offers power protection and peach of mind for up to 8 audio components. If you are investing in rather expensive high-end audio components, power ...

Knowledge is power, allowing data centers to track and correct harmonics and power factor, avoiding costly energy waste, ...

Ideally, the power factor should be 1; then the load appears as a resistor to the AC source. However, in the real world, electrical loads not only cause distortions in AC current waveforms, but also ...
